Abstract (en)

[origin: US2011198566A1] A method for manufacturing a light emitting element is directed to a method for manufacturing a light emitting element of a III-V group compound semiconductor having a quantum well structure including In and N, including the steps of: forming a well layer including In and N; forming a barrier layer having a bandgap wider than a bandgap of the well layer; and supplying a gas including N and interrupting epitaxial growth after the step of forming the well layer and before the step of forming the barrier layer. In the step of interrupting epitaxial growth, the gas having decomposition efficiency higher than decomposition efficiency of decomposition from N2 and NH3 into active nitrogen at 900° C. is supplied. In addition, in the step of interrupting epitaxial growth, the gas different from a gas used as an N source of the well layer is supplied.
